Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573068, here are decompositions:

11 + 31573057 = 31573068
31 + 31573037 = 31573068
41 + 31573027 = 31573068
47 + 31573021 = 31573068
61 + 31573007 = 31573068
89 + 31572979 = 31573068
97 + 31572971 = 31573068
127 + 31572941 = 31573068

Showing the first eight; more decompositions exist.
